Is It Time to Buy Caterpillar?

Caterpillar(NYSE:CAT) surprised Wall Street recently by reporting better-than-expected quarterly results. Sure, sales were down by 10%, but that was a big improvement over the 18% drop from a quarter before.

In the video below, Fool contributor Demitrios Kalogeropoulos gives his take on the equipment maker's latest business results, noting that both revenue and profit trends are looking up. And thanks to a pessimistic valuation and the company's big plans for share repurchases, he thinks the stock has room to rise -- even on just a small improvement in Caterpillar's results.
